"LOUIS WIRSCHING, OF NEW YORK, N. Y.

THERMO'OAUTER.

sPEcmicATm forming part of Letters Patent No. 706,482, dated August 5, 1902.

Application filed February 14, 1 902. fieri'al No. 94,028. (No model.) i

To ztZZ whom it may concern:

Be it known that I, LOUIS WIRsoHIisc, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Thermocauters, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same. p

The object of this invention is to provide an improved thermocauter which is simple in construction and operation and which may be easily and conveniently manipulated when used and which will not get out of order or frequently need repair.

The invention is also an improvement on that described and claimed in United States Letters Patent granted to me October '29, 1895, No. 548,689, and is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same reference characters in each of the views, and in which- Eigure l is a longitudinal section of my im-. proved thermooauter, and Fig. 2 a section on the line 2 2 of Fig. 1.

In the practice of my invention I provide an air-carbureter which comprises a cylindrical casing a, which is adapted to serve as a handle for the device and which is provided at one end with a removable cap a and at the opposite end with a tubular extension 0. which is screw-th readed interiorly and provided with a port or passage a Thecap a is provided with a central tubular coupling a with which is connected an air-pump or forcing device a and a the same as in the patent herein referred to, this connection be: ing made by means of a flexible tube a and said cap a is also provided in the inner side with a screw-threaded tubular coupling 5, which corresponds with the coupling a, and a central bore 5 extends through both of said couplings. I also preferably employ a tubular perforated casing c, which is screwed onto the coupling 1) and the end of which opposite the cap a is open, and in practice this perforated casing c is filled with suitable carbureting material, as in the patent referred to,

said carbureting material being not shown in this case. I

The tubular extension a at one end of the casing a forms a coupling for a tubular arm d, and this connection may be made in any desired manner; but in practice I employ for this purpose a valve-casing C1 in which is placed a three-wa valve 01, and one end of the valve-casing cl is in communication with the port or passage a and the other end thereof is provided with two ports or passages d and d, and within the tubular arm d is a small tube 6, which is in communication with the port or passage (1.

The tubular arm cl may be connected with thevalve-casing d by a sleeve '8 or in any desired manner-,aud the end of said tubular arm dopposite the valve-casing d is provided with an enlarged cantor-head g, which may be made integrally therewith or which may be connected therewith in any desired manner. Connected with the outer end of the head 9 is a conical casing giand secured to said head within said casing g is a tube 9 which projects a predetermined distance through the conical casing g and said head is also provided centrally with a bore or passage g, which extends longitudinally therethrough and with which the pipe 6 in the tubular arm at 'communicates,and said pipe 6 may be continued through the head g, as shown, and said pipe is also in communication with an interior burner-tube 9 which projects a predetermined distance into the tube g Around the inner end of the burner-tube g is an annular space or chamber gflwhich is provided d or into the tube e within said tubular arm,

and the gas which passes into the tubular arm cl passes therefrom into the space 9 within the conical casing, g and is ignited and burns around the inner end of the tube giwhile the gas that passes through the inner tube e passes out through the burner-tube g into the interior of the tube 9 and is burned in said tube 9 and the escaping gases of combustion pass out through the port or passage 9 In Fig. 2 I have shown three of the ports or passages g and one port or passage 9 but any desired number of these ports or passages may be employed.

The tube g and the tube g are preferably made of platinum, this being the best known material for this purpose, but the construction of these tubes is not absolutely limited to. the use of this material.

The carburetin g material placed in the cas ing a or in the tubular casing 0 within the cas ing a may consist of sponges saturated with petroleum, benzin, or any other suitable material, and the air is forced therethrough by means of the air-pump or forcing devices a and a The burning of the gases from the chamber g and within the tube g highly heats the said tube, and by means of the valve (1 the flow of gas may be controlled, so as to pass it through the tubular arm 01 and through the tube e within said arm, and said valve is also provided with a small groove h in one side thereof,and said valve d maybe manipulated so as to pass a small amount of gas through both the arm (1 and the tube 6, and the gas may be burned both in the annular chamber 9 within the conical casing g and within the tube 9 and said tube 9 as will be understood, constitutes the cauterizer proper.

At the end of the conical casing g is a small annular space W, and the initial ignition or burning of the gas takes place at this space, which constitutes the discharge-nozzle of the conical casing 9 and the gas may be ignited at this point, aswill be readily understood, while the ignition of the gas which escapes from the tube 9? within the tube 9 is occasioned by the heat from said tube 9 and in practice the tube 9 is first highly heated by means of the gas which escapes from the conical casing g after which the carbureted air is directed through the tube 6 and into the tube 9 where it burns within said tube, and thus maintains said tube at the degree of heat necessary in the act of cauterization.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a thermocauter, a carbureter, an airforcing device connected with one end thereof, a tubular arm connected with the opposite end thereof, a small tube placed within said tubular arm, a cauter-head connected with the end of said arm and provided with a cautertube, a conical casing connected with said cauter-head and inclosing the base of said cauter-tube, a burner-tube secured in said head and projecting into the cauter-tube, the space Within said conical casing being in communication with the interior of said arm and the inner burner-tube being in communication with the small tube within said arm, said cauter-head being also provided with an annular space or chamber around the inner end of said burner-tube and with ports or passages communicating therewith and opening outwardly through said head, substantially as shown and described.

2. In a thermocauter, a carburetor, an airforcing device connected with one end thereof, a tubular arm connected with the opposite end thereof, a small tube placed within said tubular arm, a cauter-head connected with the end of saidarm and provided with a canter-tube secured in said head and projecting into the cauter-tube, the space within said conical casing being in communication with the interior of said arm and the inner burnertube being in communication with the small tube within said arm, said cauter-head being also provided with an annular space or chamber around the inner end of said burner-tube and with ports or passages communicating therewith and opening outwardly through said head and means for controlling the flow of carbureted air through said tubular arm, and the small tube within said arm, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 12th day of February, 1902.
